The object ofV my`devi'c'e is tor make an automatic foot stool of the type that is used vFig. Bisa rear elevation of my device lbroken away '-"stool'l in section.

Vin" shoe stores, on which the shoe salesman sits and upon which thecusto'lneplaces. his foot.' A further object is to make an automaticfoot stool' that'can be madeto remain "i rear partlofl which is used lfor vthe seat for be rolled about on the Hoor `on'which it 'is @which Ai'sused Yiorgthe support of the cusautomatic foot stool that can" be moved v`'around bythe-'salesman when he Ais sitting on it, but which will be locked tol-the ffloor lj in a stationary position and one that 'can positioned.lv A further'object is Vto lmake Aan whenplthe salesman leaves his seat.' Vith `the `conventional I'foot stool -used in slicestores, when the salesman leaves his seat 'on 'j ,the stool,*the pressure ofthe foot: vofthe customer'pushes the stool away vfrom` the customer, thereby causinghim to b e forced to put his foot on the floor instead of onV the stool; By my device this is obviated because if the salesman for anyr reasonfmust arise pet has a tendency towear outl the carpet and scratch and mar the Hoor surface. With my stool there is no unnecessary movement.-

In order-'to `prevent the scratching or'1mar-it ringof the'loor and lts covering, the wheels' `of my stool-are'rubber'tiredfffA further -obing device between the stool andftheloor@ vject of my' stoolis to malte the locking 'ar- A rangement' between .the f stool .and the floor inoperative lso that lthe "stool" may* be. moved i around at will, as isfthe conventional stool on rollers, as when the floor is cleaned, etc.`

A still'further Vobject isy tomakeI-the' lockwhen the'l salesman arises from the 'stool fauthe lstool with a toolbox for' thereception of a shoe horn and shoe buttonenl-etc,

With these` and other objects in;view,"my

invention has relation tocertain novel 'eaa "tures of construction and arrangement of parts, as'will be-hereinafter more, fully p' delustrated `in the'drawings, in which,' Fig. '1 is a side elevation of my device p'artlyin section, showing' the locking devicein unlocked or inoperative! position.

vlocked' position, thatlis, in engagement' with the floor.

as to ,show a portion of the .f Numeral 4` designatesy the stool proper, vthe the Vyshoe salesman andthe vfront ypart of tom'ers foot. l `'The stool proper'isv formed of 'twol'sidemembers 5Y of the shapebest shown -1n Fig. land the front vandrear members 6 fand? respectively. -j The sideV andV front and rearmembers are secured together by nailing or other conventional means. The lower` portions' of the "sidefm'embers 5 vforni the y-feet' 8, of which there are Vfour. By means of-jthe axles 9, therubber tired wheels 10 are vrrotatively mounted on the feet 8. The front :part of the sto'ol is inclined as best shown in y Y l {F1-g1 1. The inclined member'll is secured fromhis seat on'the stool,'the pressure'of-4 *the foot of thel customer 'cannot push vthe stool' away because the stooljis locked to the floor. Furthermore," this 4unnecessary f movement of'thestool, on the floor or-car to the side members 5 'and the frontmember 6, as best shown in Fig. 1. ,This inclined =member 11 is the customers foot support. Numeral-12 designates a' stop strip secured l tothe outer endA ofv the inclined member 11 -morder to prev-ent the customers foot `from .slipping oli" the inclined member 11. The

pocket 13, -which ispreferablyma'de of metal and which is secured at one end to theunderfside'of the inclined'member 11 and at the other end tothe top 14, forms the tool box. i

ends., of the pocket 13 are secured to the side members'v 5. j The 'top 14 is rectangular Y 9o v i'nshape and is 1secured to the side members 5 andi the rear-y member 7. The device thus Vfar described forms a oot'stool that may be gfrolle'd about as is the'conventional `foot stool. All ofthe stool thus fardescribed, with the v -fexceptio'nof the wheelsy andaXles, and the t'omatic.` A still furtherv object is'"to`1supply pocket arepre lar material.

,that fitsover the top` 14. This cap is made offthe top 16 'and-the sides 17. The sides? -17 'are' of sufficient height ,so as to extendk down the side Ymembers and the lrear membery 71a short distance whenv'the top 16v isv c held in spaced relationship with the top 14. Y'The stems 18, oli' which there are four, are

secured to the underside of the top 16, near theicorners, and protrude through openings 19in the top 14, as shown in the drawing.

Numerals 20 designate U-shaped members, of which there are four, having holes formedinto the parallel portions of such size as t permit the stems 18 to pass therethrough. In org-der to accomplish tlilisQ-thelse lioles iir'nst be in alinement. These U-sliaped members Vare secured to the `underside of the immediately beneath 'the' openings 19 stlfat the stems 18 can freely be moved in the holes in the parallel portions of theU-shapd members. These U-sliaped members may' be sec-ured in any conventional'm'anner, pref- *eijablyto the side* members @bymeans of screws or bolts. Numerals 21 designate coiled springs which' ere positioned .ereund the* stems-.18 betweenr die parallel ypf0r ti r1s of the U-shaped members 20. ""J-'xllhefpurpose of vvthe coiledsprings 2 1 is to normally-hold vthe-,top ,1,6 in speeed relationship uirhthe stop 14.

The- 'arm"39 'is so Ypositioned relative the l ppening'in the rear member 7 that when the notch 38 of the angle iron 37 extends therethrough, lthat the arm 39 may be rotated into the notch 38, thereby preventing the release of the angle iron 37 and thereby holding the locking frame 25 in the position shown in Fig. l, that is to say, out of engagement with the floor 36. In order to make the clutch 30 operative, it is only necessary` to rotate the arm 39 in a reverse direction, thereby disengaging the arm from the notch 38 and permitting the angle iron 37 to pass back through the opening in the rear member 7.

WhatI claim and mean to secure by Leta cap mounted thereon for vertical reciprocation and normally held in spaced relationship with the top of th-e stool, a lock-Y through the top of said stool, a spring conl necting said locking frame and said rod, a clutch secured to said locking frame so that when a Weight is placed on the top of said stool, said clutch Will be raised above the licor on which the stool is positioned, and when the Weight is removed, the clutch Will become engaged With the floor.
